Besides, the thermal runaway behavior of the aged battery cells induced by slight overcharge is analyzed. This study comprehensively explains various side reaction effects on the battery thermal characteristic. It guides the safety design and management of Li-ion batteries during their lifespan in real applications.
Furthermore, the degradation effect is analyzed by analyzing the incremental capacity-differential voltage curves. During the high current cycling process, lithium inventory decreases significantly. Besides, the active material decreases when the battery degrades to a certain level.
However, with the degradation degree increase, battery capacity fades, TR becomes easier to be triggered by the high current rate, and TR reactions are severe. This study guides early quantitative detection, safer battery cell design, and enhanced thermal safety management. 1. Introduction
The current is defined as a positive value when the battery is charged. represents the heat dissipation power of the battery. The thermal stability of the battery material fades during the degradation process, and battery capacity also fades, which induces overcharge and overdischarge.
